Electronic and mechanical scales floor. Which ones to choose?

Mechanical floor scales have recently become an indispensable attribute in almost every home. The rapid pace of life, malnutrition lead to an increase in body weight. This is known to everyone, and therefore you need to regularly monitor the weight of your body in order to timely score an alarm, change your diet or go to sports. And to future mothers without them simply can not do.

What are the floor scales?

1. Mechanical. The main measuring tool in them is a spring that stretches under the load and turns the pointer of the scale or the scale itself (depending on the design) is directly proportional to the weight of the object. They are "reset" using a special wheel that is located at the bottom. Scales outdoor mechanical home usually have a division price of 1 kg, although there are also with 0.5 kg.
2. Electronic. According to the principle of its operation, the first electronic scales did not differ from mechanical ones, the same spring, only the result was displayed on the digital display.

The design of modern electronic scales includes two metal discs, and as a result, something like an electric capacitor is formed. Under the influence of the load, the distance between the plates changes, changing the electric charge and, accordingly, the indication of the balance. Even more modern models use a voltage sensor, representing a thin metal wire, along which an electric current resembles. If the weight is placed on the balance, the sensor's tension changes, and consequently the value of the electrical signal passing through it, which is displayed on the display. Such a design is completely devoid of mechanical parts, and all measurements are made by electronics.

All types of scales have their own strengths and weaknesses. Mechanical floor scales are less precise and much simpler in design. Because they are much cheaper than electronic ones, which by their functionality are increasingly approaching personal computers. In addition to the usual measurement of weight, electronic scales can determine the ratio of the amount of fluid, muscle and fat mass, remember the dynamics of changes in weight values and even calculate the optimal weight for each individual.

Tips and advice on choosing and using the scales

• When choosing electronic or mechanical scales floor, it is necessary to pay attention to the measuring system used in them. The scales produced in some countries, for example in the UK or the USA, often measure the weight in pounds instead of kilograms, and therefore you need to make sure they are able to switch to the usual measurement system.
• If you plan to place the scales in a room with high humidity (bathroom or sauna), it is better to choose the scales in a moisture-proof enclosure.
• It is advisable to purchase scales with a rough or corrugated surface.
• The balance must be stable. Some models have a mechanism that allows them to align on an uneven surface. Otherwise, the error in their measurement can be as high as ten percent.
• Electronic or mechanical floor scales in metal casing are more reliable and durable than plastic scales.
• Before you take the scales, you need to check the accuracy of their measurement. It is best to do this if you know your exact weight in advance, or you can weigh the packaged goods.
• Checking the mechanical scales floor, you need to quickly briefly press them, and then just as quickly release. In this case, the arrow of the balance must quickly and accurately be set to zero.

In the modern market, the choice of scales is very large, and therefore in any case you decide which is better to purchase floor scales - mechanical or electronic. Everything depends on the conditions, needs and, of course, financial opportunities.
